So I guess the real question is: do we want to merge the UNIX domain
socket locking work? The MySQL gains sound good, the performance drop
under very high load seems problematic, and there are more general
questions about performance with other workloads.
Maintaining this patch for a month or so is no problem, but as the tree
changes it will get harder.

The only thing I'm afraid of is that it'll get pushed onto the
back-burner once it's in CVS, and we'll have a mad scramble to fix
it when it's time for 7.0. That's not a show-stopper for it going
in, as there are also numerous benefits. It's just something that
needs to be tracked and worked on.
